Not every hair loss situation requires a dermatologist. But some do. Here's how to know when it's time to seek specialist evaluation—and what to expect when you do.
Signs You Should See a Dermatologist
- Sudden or rapid loss: Significant shedding over weeks rather than gradual thinning over years
- Patchy loss: Distinct bald spots rather than diffuse thinning (could indicate alopecia areata)
- Scalp symptoms: Persistent itching, burning, redness, or scaling alongside hair loss
- Unusual patterns: Loss that doesn't follow typical male pattern baldness distribution
- Young onset: Significant loss before age 20 warrants evaluation
- Treatment failure: No response to minoxidil/finasteride after 12+ months
The Rule of Thumb: Gradual, patterned thinning starting at temples or crown is usually androgenetic alopecia and can be treated with standard protocols. Anything that deviates from that pattern deserves professional evaluation.
What to Expect at the Appointment
The dermatologist will examine your scalp, possibly using a dermoscope (magnifying device). They may pull gently on hairs to assess how easily they shed. Blood tests might be ordered to check thyroid function, iron levels, or hormones. In some cases, a small scalp biopsy provides definitive diagnosis.
Questions to Prepare
- Family history of hair loss (both sides)
- Any new medications or supplements
- Recent major stressors or illnesses
- Timeline of when loss began
- Any other symptoms (fatigue, weight changes)
